Bug#36751: Segmentation fault in ctype-bin.c:308; Linux 86_64, with-max-indexes=128

Browse Source 
mysqld is optimized for the default
case (up to 64-indices); for a greater
number of indices it goes through a
different code path. As that code-path
is a compile-time option and can not
easily be covered in standard tests,
bitrot occurred. key-fields need an
explicit initialization in the non-
optimized case; this setup was
presumably not added when a new key-
vector was added.

Changeset adds the necessary
initialisations.

No test case added due to dependence
on compile-time option.
